The tourism cluster can be understood in two ways:
Horizontal –
by the creation of strategic alliances, where agreements can be of two kinds:
1. the agreements between enterprises that have the same principal activity, i.e. among enterprises that deal with entertainment, transport, catering…
2. the agreements between enterprises working with the same group of customer satisfaction, but offering different product components to the customers
Vertical – by the creation of strategic nets, where there is the establishment of a unilateral supplier/customer relation among the partners
This can be organized in such a way that the object activities of the agreement are fulfilled by one of the parts, which gives its output to the other in exchange for a payment
